The famous names are all back 4 generations or more. I put the sire in Google and did not get much for performance etc.
FWIW, the names you want to see in a pedigree need to be reasonably close up as in the first 3 generations (and yes, those horses cost quite a bit)!
This horse is NOT INbred. She is LINEbred. INbreeding requires a lot closer relatives be bred together (like 1st cousins, brother/sister, half siblings and so forth). Line breeding of this sort rarely causes issues.
Would love to see a photo of your horse.
